If you bought/plan on buying AT&T's variant of the Galaxy S4, we have some bad news for those of you who like to flash custom ROMs, kernels, and the like: it's locked down tight.

Historically, Samsung devices – up to and including the SIII – have been bootloader-unlocked on AT&T. The Galaxy S4 brings a major change in that respect, as Steve Kondik (Cyanogen) has confirmed that it is indeed locked, in that it "authenticates the recovery and boot images before executing them." In layman's terms, that essentially means that it won't allow any sort of custom recovery or boot image to be flashed and/or run.

Does anybody remember when Verizon started deploying batches of new LTE markets by the week? Well, it seems that AT&T wants to be in on some of that action. Earlier this month, the second largest carrier launched a string of new sites with the promise of several more to come this summer. As of today, new or expanded coverage came to 20 more locations.

This comes in addition to a 12 other sites that went live over the last couple of weeks.

Yahoo's self-branded app for Android – called simple Yahoo! – has just moved up to version 1.0, an update that brings with it some not-insignificant enhancements.

First among these is the app's story streams and "summaries by Yahoo!", in which news stories are parsed into bite-sized summaries. The functionality is somewhat similar to Wavii's aggregation and summarization service, but is more probably tied to Yahoo's recent acquisition of Summly. While we can't be sure just yet if Summly's handiwork is making Yahoo's app tick behind the scenes, it was noted at the time of acquisition that the summary service's technology would "soon return to multiple Yahoo!

If you've never heard of Japanese manufacturer NEC, don't worry, you're in good company. While the corporation has indeed been producing Android devices for years, some of which are quite unique and impressive, they haven't seen fit to expand most of their mobile hardware beyond Japan. (Note the complete lack of cellular devices on NEC's American page.) That's why it's so puzzling to see noted tipster @evleaks' latest break: the NEC Terrain for AT&T.

I would like to personally thank the developers of Dickorate for making an app that is slightly less-obviously ripe for the banning on the Play Store. However, avoiding cartoon imagery of naughty bits still might not be enough to save this app from the banhammer. The Dickorate app allows you to take pictures of any elongated cylindrical object you have handy and add mustaches, hats, sunglasses, and more. To save you the trouble, I have personally tested this app and included the image I took below.

Google I/O is coming! We'll know about all of Google's new projects in just 2 short agonizingly long weeks. While we desperately count the days until May 15th, we thought it would be a great idea to take stock all of the things we've caught wind of lately.

Calling this an "I/O Preview," sounds a little too certain. I'm not predicting everything here will come out at I/O, this is just a list of everything we know Google is working on - their "To-Do" list.

After a short delay, Sprint is now ushering Samsung's highly anticipated successor to the popular Galaxy S III to store shelves, but how much does it cost? New customers can pick up the Galaxy S4 with a two-year contract for $149, but existing customers looking to upgrade must plop down $249 to bring home the same phone. This isn't the best of news for current Sprint customers, but there is now another option available.

We should've seen this coming. Really, Samsung, it's our fault. We should've stopped you when you put on that incredibly sexist Broadway show. We didn't. We argued that it was funny and then even enabled you by saying you have better marketing than HTC. We set you up for this. What could we have expected except a Gangnam Style parody that touts the virtues of the Galaxy S4?

The Samsung Galaxy Note 8.0 is a strange beast. Sitting more or less between the Note II and the Note 10.1, the Note 8.0 feels like a Frankenstein Android device, mixing elements of both smartphones and tablets. Of course, that's kind of the point: in territories where carriers don't have such a stranglehold on the wireless industry, the Note 8.0 is exactly the giant phone that it looks like. Here in the States, we'll have to make due with an 8-inch WiFi tablet - a mid-sized device for the category, with a premium price.
